Re: [Paraview] Using 64 or more cores on a single node when running client/server

2017-09-13 Thread Andy Bauer
If you're running on the DSRCs I'm guessing that the limit is coming from
the node selection option (i.e. "#PBS -l select=8:ncpus=36:mpiprocs=8").
mpiprocs here is the number of MPI processes per node while ncpus is the
number of cores per node (in this case only nodes that have 36 cores per
node will be used. I've never tried having mpiprocs higher than ncpus. I
would guess that a simple MPI helloworld would really show whether or not
this is where the limit is coming from.

Best,
Andy

I am tempted to second that. There's nothing in ParaView that checks
how many cores your node has, as a result if there's a cap, it's
coming from the MPI implementation itself.

Yes, it works.

Paraview 5.4 with OpenMPI 1.7.3

konsole─┬─bash───mpirun───80*[pvserver]
├─bash
└─{konsole}

Node: 20 cores with hyperthreading.

It should be related to your mpi environment: may be oversubscribing (more than 
one mpi process by core) is not the default behavior.

Hello,

Has anyone managed to use ParaView 5.4.x with more than 64 core
on a single node when running in client/server moder.

Thanks,
